I'm starting to crank up my training intensity. I'm trying to swim three times a week with one session of drills (one-arm drills are my favorite) and one "long" swim. I try to run one interval run and one long run, and one long ride, then fill in the rest of the week with 30-60 minute runs and rides. I started taking creatine last week. I did for a month last fall and it worked out well. So far it is rough. I am constantly dehydrated, and possibly from all the water I'm drinking I am running low on salts. I suspect this because I have been cramping and that is not normal for me. I am doubling up on bananas and drinking Gatorade to correct that. My hamstring cramped up on me twice and I just do not like that at all! I am working out more intensely and as a result I'm completely sore.
